SPRIN G SUSPENSION.

No. 887,165. Specification of Letters Patent. Patented May 12 1908.

Application filed February 25, 1907. Serial No. 359,239.

To all whom it may concern:

Be it .knownthat I, JAMEs'O. WHITTLE, a citizen of. the United States of America, residing at Flint, in the count of Genesee and State of Michigan, have invented certain new and useful Improvements in Spring Suspension, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates'to improvements in vehicle springs, and more'e'speciall to springs adapted for use upon'motor vehicl es; and its object;' is to provide a simple means for supporting the vehicle frame upon elliptical springs in such a manner that all shocks and vibrations will be taken up by .the springs and not transmitted to the body, and fur-' ther to provide certainothern'ew and usefulv features in the construction arrangementan'd combination of p'arts, all as hereinafter more fully described, reference being had to the accompanying drawings 'in which Figure 1 is a side elevation of a device embodying the invention and'sho'wing the same attached to-th'e frame and axle of a vehicle; Fig. 2 is a similar view showing the spring partially compressed by the load; Fig. 3 is a vertical section ofthe same on the line w'm ndFig. 4 is ,a sectional detail of yeke's connecting the toggle and i represents the side sill oft-he frame of a motor vehicle-, 2 the axle, and 3 an elliptical spring secured to the axle'by asuitable clip a, all being of wellkno'wn construction.

Secured bysuitable clips to the inner side of the upper halfof the spring 3 is a plate 5 having downwardly extending ears between which are pivoted theupper ends of levers 6 and 7, and theselevers together with simi-' lar levers 8 and 9 which are pivoted between ears extending upward from a plate 10 se cured to the lower half of said ellipticalsprmg 'bythe clips which secure said s ring to the 45 axle, form a toggle connection etween the upper and lower halves of said spring. The pivot pins 11 which pivotally connect the outer end: of said levers are extended '-later-' ally and each formed with a vertically ex%- tending sleeveportion 12 through which a rod 13-slides freely, said rod being secured atits'ends to thelaterally bjent ends 14 of a yoke 15. ..,Coile.d springs 16 are sleeved 'upon'said' rod between the laterallyfbentends ofthe" yoke and the-pivot pin to normailly'holdsaid Trunniohs each formed with abase plate 17 by means of which it'is rigidly secured to the outer face of the sill 1, extend longitudinally outward from said sill and. form supporting pivots for the yokes, each yoke being formed with a hub or sleeve portion 18 projecting laterally from the yoke near its lower end to receive the-trunnion and turn thereon.

. The yokes together with the pivot pins 11 form supporting cranks to pivotally attach the toggle levers to the sill, said trunnions being out of axial alinementw'ith the said pins, and thus the elliptical spring, is attached to'the sill by the toggle levers only and any movement or vibration of the axle is reducedto the minimum by said levers. The coiled springs 16 also serve to yieldingly support the load'an'd absorbing vibration;

" As shown in Fig. 2, when the elliptical spring is compressed by the load, the toggle is straightened, the pivot pins 11' moving in a horizontal plane longitudinally. of the sill and thus the yokes rock on their trun'nions.

to ermit of such movement.

f desired the coil springs 16 may be dis pensed with' and a plain crank used to sup-.

portthe sill and permit the straightening of I the toggle". a

Having thusfully described the invention what I claim is 1.' The" ombination with an elliptical spring, of toggle levers "connecting the membersof said spring, and means forattachin the connected ends of said levers to a silmovable longitudinally 'ofthe si'll adapted to transmit lateral movements of the sill in eitherdirection parallel to the plane of the spring to the said lever ends.

2. The combination. with an elliptical.

spring, of levers connected at one end to the two members of the spring and pivotally connected together at their opposite ends, members pivotallyattached to the levers at their.

pivotal connection and to a sill to rock there on, adapted to transmit lateral movementof the sill in either direction parallel to the plane of the spring to the said' lever ends.

3. The-combinationwith a sill and an elliptical spring, of toggle levers conneotingthe members of the spring, pins'form ng the p vots thereof extending l'aterall from the connested ends of said levers an means secured.
